The inorganic nutrient solution consisted of complete plant nutrients prepared from soluble grade commercial fertilizers with a chemical composition of (mg l-1): N 180, P 40, K 250, Mg 50, Ca 150, Fe 2, Mn 0.75, Cu 0.1, Zn 0.5, B 0.4 and Mo0.05. The EC of the inorganic nutrient solution ranged between 1.8 and 2.2 mS cm-1. Locally available substrates were used in the trial. Perlite was horticultural grade, 2 and 5 mm and supplied from Eti Holding Inc., Izmir, Turkey. Basaltic pumice with 1–3 mm particle size was provided from Kula, Manisa, Turkey. The natural clinoptilolite mined in Go¨rdes by Enli Madencilik Inc., Manisa, Turkey consisted of mainly clinoptilolite mineral and traces of feldspars and quartz with a cation exchange capacity of 0.95–1.40 mmolc g-1 and a particle size of 1.8–3.5 mm. Mixtures were prepared on volume basis and placed in 24 l horizontal plastic pots. Two plants were grown in each pot providing a planting density of 3.3 plants per m2, and consequently each plot had 12 plants.
